Each collimated LED consists of a complete, ready-to-use assembly that is comprised of a high-power LED mounted to a heatsink, collimating lens, and lamphouse-port-compatible housing. Thorlabs' collimated LEDs are designed for use in condensing, projecting, and other illumination applications. The aspheric collimation optic used in each assembly offers superior aberration correction and low f-numbers for higher light gathering efficiency. The coated aspheric lenses are ground and polished on the plano side and precision molded on the aspheric side. All that is required for these LEDs to operate as a complete lamp replacement system is an LED driver and power supply.

Spectra for the Available Wavelengths*

Plot showing the Emission spectrums of the LEDs

*) Due to variations in the manufacturing process and operating parameters like temperature and current, the actual spectral output of any given LED will vary. This plot is only intended to be used as a guideline.

Thorlabs' collimated LED assemblies can easily be connected to standard and epi-illumination ports on most readily available commercial microscopes, including Leica, Olympus, Nikon, and Zeiss. Please see the Specs tab for details. The LED in the collimator assembly can be quickly interchanged by unscrewing the LED housing and replacing it with any of our mounted LEDs.

Thorlabs offers four drivers, LEDD1, LEDD1A, DC2100, and LEDD4 (requires LEDD4-HUB), that can be used with these collimated LEDs. The DC2100 and DC4100 can read the EEPROM chip in the mounted LED. This automatically limits the max. output current of the driver to the max. LED current to protect the connected LED from damage. Please see the LED Drivers tab for more information on each driver option.

A response from Ken at Thorlabs: Our new DC2100 is also plug and play compatible with these LED light sources.

Poster: acable	Posted Date: 2009-10-03 15:47:55.0
Is the LEDD1 driver the only driver you offer that is plug and play compatible.
